Find the time requried to liberate 1.0 litre of hydrogen at STP in an electrolytic cell by a current of `5.0 A`.

The number of moles of H_(2) in 0.224 litre of hydrogen gas at STP is

The volume of 1.0 g of hydrogen in litres at N.T.P. is

Mass of 1 litre of hydrogen at STP is 0.0896 g. Calculate the value of R from this date.
